The Linux-based OS powering the One Laptop Per Child's XO laptop is now available for free download.Weighing in at a paltry 291MB, it gives OLPC developers and any other curious individuals a glimpse of the experience the "$100 laptop" will offer. For those that don't wish to check it out personally, screenshots are available from LinuxQuestions.org showcasing the interface and some applications including the lightweight web browser. While the operating system isn't designed to support hardware outside of the XO's specifications, it runs remarkably well on a variety of machines - at least well enough to allow prospective coders to test their applications for hopeful submission into the OLPC's development site.
